ObjectiveTo evaluate the therapeutic effect of encircling constriction of superficial femoral vein in the treatment of primary deep venous insuficiency(PDVI).MethodsFrom Jan.2004 to Jun.2011,187 patients( 196 lower extremities)with primary deep venous insufficiency were treated with encircling constriction of venous wall at the first pair of superficial femoral venous valve pulse superficial varicose stripping.Results The 183 limbs in 176 patients were followed-up from 7 months to 8 years,with a mean period for 63.5 months.Ninety-four point one percent of the patients were followed up (176/187).Clinical symptomatic improvement achieved in 87.4％ ( 160/183 ) of the lower extremities.There was 2.2％ ( 4/183 ) of recurrence of the varicose vein,9.3％ ( 17/183 ) of light edema,8％ ( 2/25 ) of recurrence of ulcer.ConclusionEncircling constriction of superficial femoral vein is an effective method in the treatment of primary deep venous valve insufficiency.

Objective To evaluate endoscopy for the diagnosis of primary gastrointestinal mucosaassociated lymphoid tissue lymphoma (MALT lymphoma) and diffuse large B-cell lymphoma (DLBCL).Methods The clinical pathology,hematological/biochemical studies,and endoscopic data of 98 primary gastrointestinal MALT lymphoma and DLBCL patients from Aug 2010 to May 2017 were analyzed retrospectively.Results 17 patients had higher than normal LDH blood level (＞270 U/L).47 patients were Helicobacter pylori (Hp) positive;Gastrointestinal endoscopic study,including endoscopic mucosal resection (EMR)/endoscopic submucosal dissection (ESD) and endoscopic ultrasonography established diagnosis of MALT lymphoma and DLBCL in 96 out of 98 cases (98％).The endoscopic manifestations of MALT lymphoma and DLBCL were ulcerative,uplift,diffuse and infiltrative,and erosive,with ulcerative type as the dominant one.The follow-up examination showed that the survival ratio (88％) of MALT patients was higher than that of DLBCL(68％),and more patients with lower Ann Arbor stage survived (92％) than those with higher Ann Arbor stage (64％).Conclusion Endoscopic biopsy together with endoscopic ultrasonography makes definite diagnosis of MALT and DLBCL.

Objective:To investigate the effect of continuous use of aspirin on gallbladder function and thromboembolism risk in the patients undergoing laparoscopic cholecystectomy. Methods:Totally 100 patients undergoing laparoscopic cholecystectomy from October 2010 to October 2014 were selected as the subjects. All the patients were given aspirin for a long time and randomly divided into two groups. The patients in the observation group were treated with aspirin continuously, and the control group suspended aspirin 7 days before the surgery and administrated aspirin continuously after the surgery. The perioperative thromboembolism,changes in gallbladder function and coagulation function, and intraoperative and postoperative differences in the indicators were compared between the groups. Results:The gallbladder volume in the observation group decreased, and the gallbladder contraction rate and emptying index were higher than those on the 7th day before the surgery(P < 0.05). The above indices were significantly better than those in the control group (P < 0.05). There was no significant change in the coagulation function after the treatment in both groups(P >0.05). There were no significant differences in the operative time,intraoperative blood loss, postoperative drainage and postoperative hospital stay between the groups (P > 0.05). The total incidence of perioperative thromboembolism in the observation group was 2.0%,which was significantly lower than that in the control group(P< 0.05).Conclusion:Continuous use of aspirin during laparoscopic cholecystectomy is beneficial to reducing the volume of gallbladder, promoting gallbladder emptying and reducing the risk of perioperative thromboembolism. The reasonable use has no obvious effect on the postoperative coagulation function.
